"I was always wondering why it is recommended to hover at ~50% max. throttle? Also, I was always wondering why people are checking max. thrust for evaluating max. lift capability? Propeller/motor has a max. efficiency at ~20% of its max. thrust. So,…"

"Hi there, as an aero engineer myself I like your approach. Don't get bogged down with math just yet, just look at the data. First question is to ask how accurate your test is, i.e. how do you accurately measure battery life? At what point is it…"

"@Ted: required power scales to the power 3/2 with the total weight, available energy scales with the mass of added battery. With some boring math hocus pocus you'll end up with a battery that weight twice your empty mass. Perhaps I can write it…"

"Good Kieran: take in mind that your settings changes with different weight, check your temperature components with higher weights not to damage them, different setups type affect in different proportion the added weight; Eg one test I did with my…"

"Theoretically , 66% of the total weight should be battery. In other words: multiply your drone's weight without battery by two and take this amount of battery. In practice, 50% will do because most of the times your propulsion system will not…"

"It could be interesting also to measure battery weight vs flight time, because there should be an optimal value for optimizing flight time. (small battery = shorter flight time, large battery = shorter flight time too because of the added weight)"

Brief introductionHello everyone,To pass my middle school, I am required to complete a project of my own choosing. I chose to buy a quadcopter and then carry out an experiment with it. This was the first quadcopter that I have bought and I had no previous experience of quadcopters. This forum has been immensely helpful about everything from, what quadcopter I should buy, how to fly a quadcopter and smaller things such as should I purchase a different battery. Because this forum has been really…See More
